Before this patch, when you objdump an LLVM-compiled file, objdump tried to decode data-in-code sections as if they were code. This patch adds the missing Mapping Symbols, as defined by "ELF for the ARM Architecture" (ARM IHI 0044D). Patch based on work by Greg Fitzgerald. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169609 91177308-0d34-0410-b5e6-96231b3b80d8

@ .wibble should *not* inherit .text's mapping symbol. It's a completely different section.
